sorry for my english!!

and thanks for the answers!

Ok, what you need to learn to use is Qt's grid system. This will automatically resize and fit the application. Look for the button that looks like 3x3 squares.

Better yet: focus on your whole dialog, and press Ctrl+G. Right click on the part you don't want and click on Remove.

Hi,

#1: Catchword "Layout". Look in the documentation for "Layout Management".
#2: See QStatusBar::sizeGripEnabled
#3: See #1
